如何获取UIImage的大小(KB)

Question

我正在从中获取图片didFinishPickingMediaWithInfo.

UIImage *originalImage = (UIImage*)[info valueForKey:UIImagePickerControllerOriginalImage];

我想在Kb中获得Image的大小.

Answer 1

    UIImage *originalImage = (UIImage*)[info valueForKey:UIImagePickerControllerOriginalImage];
    NSData *imgData = UIImageJPEGRepresentation(originalImage, 1); //1 it represents the quality of the image.
    NSLog(@"Size of Image(bytes):%d",[imgData length]);
    imgData = nil;
